Salience and Frontoparietal Network Patterns in Children with Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder
… functional connectivity. In specific, two brain networks have been implicated in these disorders: the salience network (SN) and frontoparietal network (FPN). The SN is a network anchored by bilateral anterior insula and the dorsal anterior cingulate cortex and has been implicated in “bottom-up” …

Spatiotemporal Dynamics of Working Memory: Eros-Based Comparisons of Frontoparietal Network Activities in Preparation, Encoding, and Recognition Tasks
… Results of this study demonstrated that the frontoparietal network occupies a central role in domain-general working memory, and furthermore that the spatiotemporal dynamics of this network are indeed common across both similar and disparate working memory paradigms. Moreover, we found that …

A Multimodal Investigation of Age Differences in Inhibitory Control
… changes in the structure and functioning of the frontoparietal network that supports cognitive control processes. This thesis examines the relationship between the white matter properties and functional recruitment of the frontoparietal network and their association with performance on cognitive …

The Role of the Multiple-Demand System in Fluid Intelligence and Selective Attention: Insights from Lesion and Neuroimaging Studies
… the multiple-demand (MD) system, a distributed network of predominantly frontoparietal regions, plays a critical role in this process. A growing body of evidence shows the MD system is consistently recruited in response to a wide range of cognitive demands and preferentially represents …

Increasing Screen Exposure Time Harms Inhibitory-Control Network in Developing Children: A Two Years Follow-up of the ABCD Study
… delay the development of the inhibitory control networks in children, who are vulnerable to immediate reward-orientated tendencies and not yet capable of controlling their impulsivity. Therefore, it was hypothesized that as children become more exposed to screens, the development of the …

Testosterone administration increases the size of womens' peripersonal space: An embodied index of social dominance
… surrounding the body, encoded by a specific frontoparietal network of multimodal neurons. Stimuli in PPS are represented in a body-part centred manner in terms of possibilities for action, and PPS representations function to facilitate defensive and/or approaching responses to stimuli. The …

Emotional and Cognitive Influences on Visual Search
… the seed regions amygdala, V1, and V2 with networks in the brain corresponding to cognition, particularly visual attention. Nineteen subjects performed the search task during fMRI, while their eye movements, pupillometric data and manual responses were measured. Furthermore, the subjects …

The interplay between selective attention and working memory: A behavioural, neural and computational perspective
… studies have observed a highly similar frontoparietal network subserving both processes, indicating anatomical and functional overlap in their corresponding neural mechanisms. Nevertheless, despite substantial evidence for cognitive and neural overlap, almost everything we know about the …

Relationship of brain functional, structural and vascular patterns to cognition in ageing and dementia
… connectivity? 2) Do the patterns of functional network topography, brain structure and cerebral blood flow have independent or synergistic effects on cognitive function in healthy ageing? 3) Do the patterns of functional network topography, brain structure and cerebral blood flow have …

Elucidating the Principles of Brain Network Organisation through Neurosurgery
… as a model to study the principles of brain network organisation through neurosurgery. Specifically, I combined insight from a normative cohort of healthy individuals across the lifespan with a highly rare neurosurgical cohort of diffuse glioma patients who underwent longitudinal connectomic …

Examining the Transient Neural Dynamics Underlying Working Memory Maintenance for Complex Visual Stimuli

A fast optical imaging study of frontoparietal preparatory dynamics in response-mode switching
Coordination between networks of brain regions is important for optimal cognitive performance, especially in attention demanding tasks. With the event-related optical signal (EROS; a measure of changes in optical scattering due to neuronal activity) we can characterize rapidly evolving network …
